Surface-area changes of glaciers in the Tibetan Plateau Interior Area since 1970s using recent Landsat images and historical maps. Annals of Glaciology.This dataset contains the contemporary glacier inventory of China, which was compiled totally based on Landsat TM/ETM+ imageries acquired around 2007. All the Landsat imageries were obtained from USGS websites (http://glovis.usgs.gov, and http://earthexplorer.usgs.gov). The glacier outlines in this dataset were semi- automatically extracted by widely used band ratio segmentation methods and improved by multi-rounds manual works.
In current version (V1.0), this dataset includes 42,359 glaciers with a total area of 42,938 km2, distributing in seven large exorheic river basins (i.e. Ertix River, Yellow River, Yangtze River, Mekong River, Salween River, Ganges River, and Brahmaputra River) and six inland basin systems (i.e. Hexi basins, Qadam basins, Tarim basins, Jungar basins, Turpan- Hami basins, and Tibetan Plateau interior basins). The dataset includes a set of attributes characterizing each glacier, includes GLIMS ID, drainage basin code, first glacier inventory ID, glacier area and perimeter, latitude and longitude of glacier central point, maximum, mean, minimum, and median area elevation in glacier-covered topographies, mean slope and aspect, primary and auxiliary data source, and date tag of the glacier. The glacier topographical parameters were calculated from SRTM V4 DEMs.This dataset is the main products of the MOST (Ministry of Science and Technology of China) project “Investigation on glacier resources and their changes in Western China” (2006FY110200), which was launched at 2006 and finished at 2011. This project is directed and executed by Cold and Arid Regions Environmental and Engineering Research Institute (CAREERI), Chinese Academy of Sciences (CAS). Participants of this project include Institute of Geographic Sciences and Natural Resources Research (IGSNRR), Institute of Tibetan Plateau Research (ITP), and Institute of Remote Sensing and Digital Earth (RADI) of CAS, and Lanzhou University (LZU) of Ministry of Education (MOE) of China. The compilation of contemporary glacier inventory of China is one of its objectives. The dataset was released for open use after the end of this project to fulfill the wide demands of the glacier data in different fields.Users of this dataset must have a clear statement in their publications (papers, books, reports, etc.) of the original data source and adopt the references style provided in the reference section. The suggested data source citation is as follows: This dataset is provided by “Investigation on glacier resources and their changes in western China” (2006FY110200) and “Glacier change monitoring and its impact assessment research in western China” (KZCX2-YW-301).GlacierGlacier InventoryGlacier changeChinaGlacier Area2005GeographyGlacierf92a4346-a33f-497d-9470-2b357ccb4246_s.pngthumbnailpngf92a4346-a33f-497d-9470-2b357ccb4246.pnglarge_thumbnailpng73.2105.5552652749.62005-01-01T16:53:002005-12-31T16:53:004326
